Just as God has set light in opposition to darkness so is Thanksgiving in opposition to covetousness (which is idolatry). Though no one is jailed for covetousness, it might well cause more people to miss heaven than any of the other commandments. Have your eye singly focused on God’s will for your life. From I Timothy 6:10 he explains that the love of money (and any type of gain) is indeed the root of all evil.
